One of my hobbies is home beer making.
Its great fun and has three enjoyable aspects
1) Brewing it
2) Drinking it
3) Giving it away to friends. Free beer-instant popularity!
Here is a short film about how to do it.
"The Universe is an infinitely interesting place. Unfortunately life is too short and we are too preoccupied with the necessities of existence to see and understand than the tiniest infinitesimally small piece of it."
